For a sustainable future, efficient solar energy harvesting and storage is required. Solar hydrogen production from photoelectrochemical water splitting is a promising technology and, in particular, cuprous oxide photocathodes are interesting photoelectrod ...

Elsevier Science Bv2016

Concentrating solar irradiation for use in integrated photo-electrochemical devices potentially provides an economically competitive pathway for hydrogen generation, even with partial use of rare material components. Heat transfer and thermal management ar ...

Electrochemical Soc Inc2016

The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...

EPFL2016

Hematite (alpha-Fe2O3) is a promising semiconductor as photoanode in solar hydrogen production from photoelectrolysis of water due to its appropriate band gap, low cost and high electrochemical stability in aqueous caustic electrolytes. Operation of such p ...
